FIGQ. E-

FIGl

place, The connecting piece G has a vertical opening therein in which the lower end of the tube E is seated and has a horizontal opening in which is received the elbowshaped tube P, which extends beyond one face of the connecting piece G and forms a nipple I, to which the similar end J of the elastic tube Q is connected, said tube Q having a flared end 0 for attachment to the faucet of a barrel or other liquid containing receptacle,

The connecting piece G is shouldered upon its under side to form a reduced exten sion K fitting Within the sleeve L on the base M of the standard, and said sleeve is engaged by the set screw N to adjust the standard. 7

From this construction, it will be seen that the device is of simple and inexpensive construction and may be easily carried from place to place to measure the contents of the barrel, and in operation the tube Q is connected with the faucet of the barrel and the liquid flou's into the glass sight tube E until it has attained a level equal to that of the liquid in the barrel. This level is easily read by reason of the graduations on the supports for the tube E. and the contents of the barrel may thus be readily determined. Tire scales on the supporting rods may be of any desired character and contain any desired sets of graduations. While the rods may be adjusted vertically with repended claims, may be resorted to when found necessary and desirable.

I claim:

In an invoice rod, the combination with proximate parallel scale strips having each a groove in its inner face, a tube fitting in said grooves, a connecting-piece connecting the scale strips at the top, a connecting piece connecting said scale strips at the bot tom, said bottom connecting piece having a depending extension and also an opening at one side, broad base having a sleeve to receive the extension in said bottom connecting-piece, a finger-operated clamping screw in the sleeve to engage the extension for securing the device to the base, and a flexible tube connected with the opening in the side of the bottom connecting piece.
